Meissen's LT1 Build-up Thread

[Boost Addict]

LT1 and SBC oil pumps are COMPLETELY different from LS1s... they are nowhere near the front cover.


Yes it does, the spring controls the pumps pressure bleedoff. So the stock spring will peak at 40psi even though the pump is generating more. With my white spring, i have SUBSTANTIALLY better oil pressure. While cruising i have around 60 PSI now, whereas it barely exceeded 40 even at WOT with the stock spring. Cold itll even hit 70. I did however delete my oil cooler at the same time which can be worth a couple PSI.


You shouldnt have any problem figuring out where the spring goes once you remove the bump brian. BE SURE TO TACK WELD THE PUMP BACK IN PLACE so you dont have it falling off on you like happens randomly to many people. Unfortunately for me, i didnt know about that when i did mine.

Tack weld the pickup tube you mean?

I know that you guys moved past this already but just thought i would say, when we had to dyno engines for my engines class a couple degrees for a cam can increase power throughout the band by quite a bit. Anyways looks sweet.... I hate looking at this thread because it makes me want to buy a v8 so bad. Well keep it up B and hope all goes well with the rest of the instal.

[meissen]

Thank you, sir!

Your motor didnt come with injectors?

[meissen]

It did but I got 30lb'ers. Steve said to just upgrade now - that way if my stock injectors couldn't handle the cam and tune that I'll already be set.

Ya, never hurts to be a bit big with fuel injectors.

Sorry, you'd be wrong.

It's red but the camera doesn't want to get any good pics. The red was painted on first in a few layers, then I polished up the fins, and these pics were taken right after I sprayed a few coats of clear coat engine enamel on.

[JoeliusZ28]

intake looks good! yea i agree with upgrading your injectors. Mine are probably maxed right now - im going to find out soon enough when i start playing with the tune this spring.
